  • Background: Shoulder stabilization commonly involves two components: the glenohumeral stabilization exercise (GSE) and scapular stabilization exercise (SSE). Despite the fact that the shoulder stabilization has advantageous merit, to our knowledge, only a few studies have compared the superior of the GSE and the SSE. Objects: The purpose of this study was to assess the effects of GSE in patients with nonspecific shoulder pain. Methods: Thirty subjects with nonspecific shoulder pain were randomly divided into an experimental group and control group, each with 15 patients. The experimental group used an GSE, whereas the control group did SSE. All subjects were measured in shoulder stability, scapular symmetric alignment, pain, muscle power, and range of motion before and after the intervention. Results: GSE resulted in significantly better shoulder stability (p=.046, from $8.67{\pm}7.54$ score to $13.93{\pm}9.40$) in the experimental group compared with SSE in the control group. However, no significant effects were observed for scapular symmetric alignment including the angles of inferior scapular distance (p=.829) and inferior scapular height difference (p=.735), pain (p=.113), muscle power including shoulder flexion (p=.723) and abduction (p=.897) and range of motion including shoulder flexion (p=.853) and abduction (p=.472). Conclusion: These findings suggest that GSE may be more effective in increasing the shoulder stability than the SSE in patients with nonspecific shoulder pain, probably through a centralization effect on the shoulder mechanism.

  • Background: The purpose of this study was to determine the effects of massage, stretching exercise, and scapular stabilization exercise in patients with upper trapezius myofascial pain syndrome (MPS). Methods: Twenty-three female patients with upper trapezius MPS were randomly allocated to three groups: massage, stretching exercise, and scapular stability exercise groups. Therapeutic intervention for all groups included general therapy such as hot pack, transcutaneous electrical nerve stimulation and ultrasound. Patients in the massage group (n=8), stretching group (n=7), and stabilization exercise group (n=8) received their respective therapy program after general therapy for 15 minutes. Therapeutic intervention for each group was performed three times per week for six weeks. All groups were tested four times: prior to the test, at three weeks, at six weeks, and at nine weeks. Results: Pain levels decreased significantly in the stretching and stabilization exercise groups over time (p<.05). The rate of change in pain level was significantly different among all groups (p<.01), and the stability exercise group experienced the lowest pain level. Pressure-pain level increased significantly in the stabilization exercise group over time (p<.05). The rate of change in pressure-pain level was significantly different among all groups (p<.01), and the stability exercise group had the highest pressure-pain level. The level of upper-extremity stability increased significantly in the stability exercise group over time (p<.05). The rate of change in the upper-extremity stabilization level was significantly different among all groups (p<.01), and the stability exercise group had the highest upper-extremity stability level. Conclusions: Scapular stabilization exercises proved to be the most effective therapy for MPS patients.

  • Background: Scapular posterior tilt (SPT) is important in the prevention of abnormal scapular movement and pain during elevation of the arm. However, previous studies have overlooked increased upper trapezius (UT) muscle activity interrupting the normal force couple of scapular motion and compensation of levator scapulae (LS) muscle activated simultaneously with UT during SPT exercise. Objects: The purpose of this study was to compare the effects of modified SPT with depression exercise versus SPT exercise on serratus anterior (SA), lower trapezius (LT), UT, and LS muscle activities and the clavicular tilt angle, in subjects with rounded shoulder posture (RSP) and myofascial pain in the UT muscle region. Methods: Eighteen subjects with RSP were recruited and randomly allocated to 2 groups; 9 in the SPT group and 9 in the SPT with depression group. All subjects met the specific RSP criteria and had myofascial pain of UT region. Depending on the allocated group, subjects performed the assigned SPT exercise and EMG data were recorded during the each exercise. Clavicular tilt angle was defined as the angle between the line joining the medial and lateral end of the clavicle and a horizontal line. Results: The SA muscle activity was significantly greater in SPT with depression than with SPT exercise (p<.05). The UT, LS muscle activity and the clavicular tilt angle was significantly lower in SPT with depression than with SPT exercise (p<.05). Conclusion: These findings were insightful because the potential risk of pain from overactivation of the UT and LS was considered, in contrast with SPT exercise. SPT with depression exercise can be implemented as an effective method to facilitate scapular muscle activity for stability and to prevent myofascial pain in the neck and shoulder.

  • Purpose : The purpose of this study was to find out the effect of exercise on the angle and distance between scapular stability and McKenzie stretch exercise. Method : 30 volunteers took part in this experiment and we divided into three groups(experimental group A, experimental group B, control group C). Experimental group A performed scapular stabilization exercise and experimental group B performed McKenzie neck stretching exercise and control group didn't perform any exercise. Experimental group(A, B) received a total of 12 exercise session over a 4 week period (three times per week). Posture and craniovertebral angle changes of the neck using GPS measurements reported. Result : The CVA and distance change after exercise were significantly reduced in the experimental group A and B. Conclusion : Therefore, we have confirmed through experiments reducing a CVA and distance between scapular stabilization and McKenzie neck stretching exercises, whereby we would also be helpful to ensure the treatment of forward head posture.

  • Background: The scapulo-thoracic musculatures including serratus anterior (SA), upper trapezius and lower trapezius can provide shoulder stability and functional shoulder movement. Objects: The muscle activities of upper and lower SA were compared during three different scapular protraction exercises in healthy individuals in sitting position. Methods: Twenty-five healthy subjects were participated. Electromyography device was used to measure muscle activity of upper and lower SA and trapezius muscles. Each subject was asked to perform three different scapular protraction exercises (scapular protraction [SP], SP with self-resistance [SPSR], SPSR with hand-exerciser [SPSRH]) in random order. One-way repeated measures analysis of the variance and a Bonferroni post hoc test were used. Results: The muscle activity of lower SA muscle was significantly different among three conditions (SP vs. SPSR vs. SPSRH) (p < 0.01). The lower SA muscle activity was significantly greater during SPSRH compared to SP and SPSR, which required joint stability more than SP and SPSR (p < 0.01). Conclusion: SPSRH exercise can be recommended to facilitate the muscle activity of lower SA. In addition, the intramuscular variation in the upper and lower SA during scapular protraction exercise is required to consider the effective rehabilitation.

  • Background: This study was conducted to investigate the effect of leg lift difference on the serratus anterior muscle and the upper trapezius muscle when a subject with winged scapula performs a scapula protraction exercise in a four-leg crawling posture. Method: Twenty normal adults and 20 subjects with winged scapula participated in the experiment. Surface EMG recordings were collected from serratus anterior muscle and back trapezius muscle during scapula protraction exercises. Scapular winging is measured with the lifting distance of scapula retraction to the back using an electronic digital caliper. In two groups of four-leg crawling posture, the two legs support, the dominant leg lifting, and the non-dominant leg lifting, including the scapula protraction, were performed. To examine the difference between groups in the variance analysis, the Bonferroni correction was used (significance level ${\alpha}=.017$). Statistical significance level ${\alpha}$ was .05. Results: There was a significant difference in serratus anterior muscle and upper trapezius muscle during push-up plus exercise in leg lifting in four-leg crawling posture, but there were no significant differences in muscle activity between serratus anterior muscle and upper trapezius muscle, and there was no significant difference according to the presence or absence of scapular winging. Conclusion: For the shoulder stability of the ipsilateral side with the serratus anterior muscle, the leg-lifting posture is effective in the four-leg crawling, and also when a subject with winged scapula chooses an exercise, lifting the ipsilateral side of leg with scapula protraction exercises at the same time may have a positive effect on scapula dysfunction.

  • This study was to investigate whether a trunk correction taping plus scapular setting exercises has an effect on trunk muscle activation and trunk balance and upper extremity function in patients with stroke. Twenty stroke patients were randomly divided into a trunk correction taping with scapular setting exercise group (n=10) and a scapular setting exercise group (n=10), and each group performed given interventions for 30 minutes for 4 weeks. In the experimental group, there were significant increases in muscle activation, K-TIS, and MFT (p<.05), and a significant improvement was detected in K-TIS and MFT compared to the control group (p<.05). This study suggests that a trunk correction taping with scapular setting exercises was more effective on trunk muscle activation, trunk balance, and upper extremity function in stroke patients compared to a scapular setting exercise. It could be clinically more significant if the change in the onset time of muscle activity is confirmed in the further researches.

  • Purpose: The purpose of this study was to determine how a shoulder complex stabilization exercise affects ball control and ball speed in elementary school baseball players with an instable scapula. Methods: The subjects of the study were 16 baseball players attending S elementary school in Kwangju Metropolitan City. A shoulder complex stabilization exercise was conducted three times per week for one hour for four weeks. Then, the participants were divided into a scapular instability group or stability group based on their lateral scapular slide test scores. The measurement tool was measured using the target, the ball speed tester (PR1000-BC). All inspections were measured before and after the mediation period to examine the change in the subjects according to the mediation period. Results: As a result of measuring ball control, there was a statistically significant difference in the variation over time (p < 0.05), and there was no statistically significant difference in the interaction between time and group (p > 0.05). As a result of the test of effectiveness between subjects, there was no statistically significant difference found among the groups (p > 0.05). In terms of ball speed, there was no statistically significant difference found in the variation over time (p > 0.05) as well as in the interaction between time and group (p > 0.05). In terms of the effectiveness between subjects, there was no statistically significant difference found among the groups (p > 0.05). Conclusion: It was found that the shoulder complex stabilization exercise could improve ball control for elementary school baseball players. It is believed that this will help prevent and solve possible sport damages experienced during training or competitions, thereby helping athletes use training methods to improve their exercise capacity and continue their careers.
